> Hello,
>
> I did a quick test with 3 pcs russian REW14 coax relays. The setup was
> very simple:
> HP432A power meter, two attenuators (-30dB) and transceiver.
> Measured results
> (isolation) are:
> -----------------------------------------
> 144 MHz
> - 44,6 dB -45,3dB - 45,7dB
> -----------------------------------------
> 432 MHz
> -34,8dB -35,4 dB - 35,8dB
> ------------------------------------------
> 1296 MHz
> -24,7 dB -25,4dB -25,7 dB
> -------------------------------------------
> Note: this is the isolation with quite correct loaded relay outputs, I
> did not check the SWR,
> but the attenuators are very good quality (50 ohm) up to 10 GHz. The
> isolation has not been
> checked with worse SWR.
